Summary:
The Lisk API has the ability for a delegate to see which accounts voted for him. This, along with the new Lisk forging rewards, opens up the possibility for delegates to do profit sharing with those who vote for him. What I have in mind is how I originally thought DPoS would operate with Bitshares and should have run with Crypti. I would like to offer to split the delegate earnings with the people who vote for my delegates based on how much they have in the Lisk accounts they vote from on a running basis and how much they dilute their votes by voting for other delegates. So this would be truly a PoS type system where stake holders receive a return on their holdings with a portion going to the delegates they choose to represent them. This will also incentivize people to hold Lisk since it can offer them a return.
That's actually a great idea as far as I can tell!
As far as I see, it is a bad idea: The delegates are the backbones of the curriency. If the backbone isn't stable and fast, the whole ecosystem will break down. The delegate fee is a payment for the delegates to offer this stable and fast ecosystem. If there is some overhead, which the delegates can share, then the fee is to high.
But I don't want, that the delegates should be chosen because one offers 3 satoshi more than others. They should be delegates because they proof, that they can offer a stable,fast and trustfull service.
